After ⚪ centuries will this puzzle make a good New Year puzzle?

Rules:

1. Normal Sudoku rules apply.

2. (Region-Sum-Product cages) Box borders devide a cage into segments, each having a sum, and the product of all sums is given. Digits may repeat in a cage if allowed by other rules.

3. (Kropki) A white dot indicates the difference of digits it separates (along the line, elsewhere the lines are cosmetic). A black dot indicates the ratio of digits it separates (in any order).

4. Two big circles contain the same digit.
